Two corrections:1. In Russian, MK stands for "microcomputer". 2. MK-85 has the body cloned from Casio but it''s absolutely different inside. MK-85 is 16-bit and it''s compatible (to a degree) with DEC PDP boxes. E.g. one of its variations was used for strong cryptography (to wire money transfers via unsafe public networks).

Original design of MK-85 (with misleading name MK-87) has nothing common with Casio: http://www.computerra.ru/upload/apismenny/elektronika-mk-87-1.jpg

This was cloned down to the buttons by the Soviets as the Elektronika MK-85....probably had different guts (the Soviets had round microchips for calculators for some reason.)

"MK" stands for "mark." Elektronika was a stock name for electronic gadgets made in the USSR that weren''t radios.
